public computer = no page load

Hi, I have just started all this nomadic behaviour, simply because I am ditching my PC and am having to think of ways to get by using, eugh, public computers. FF on a USB seems good to me, especially with all the etx.!!!

Problem is IE's tools menu is blocked from access, and I cannot load the page in FF because I do not know the proxy settings. I have been scouring the net for a tool that can posibly get that info externally.

Can anyone help?

Thanks,
